Rich metadata is added to the code generated by YouTube Embed. This gives details about the video for the purposes of search engines and other rich content interests.
To test the results you can use the Google Rich Snippets Testing Tool.
For Google to pick up the metadata you must apply to be whitelisted.
By default, WordPress will process YouTube URLs which have been added to their own line in a post. The result will be an embedded video but with few parameter available for customisation.
By ticking the URL Embedding option in General Options, YouTube Embed will take over this processing of URLs and apply standard customisation, as per all other types of embedding. Under this tick box there is also an option to specify a different default profile.
Unlike all other types of embedding, YouTube playlists cannot be used.
Select this option to allow people to add YouTube videos to their comments. All they have to do is to add a YouTube URL on a separate line and it will display. Under this tick box there is also an option to specify a different default profile.
The Chromeless player uses the Flash AS3 player but removes all controls and styling from the resulting video. It has the same restrictions as the standard AS3 Flash player and some of the profile options may not work as usual – e.g. the option on how to display player controls, due to the fact that there aren’t any.
The Chromeless player can be recreated by switching off controls and all other styling for other video types. However, once a video has been started in the Chromeless player the user cannot stop it – this cannot be created with other player types.
EmbedPlus is an alternative embedding method which adds new features to the standard player. The best way to learn about these new features is to visit the website.
EmbedPlus does not support non-Flash methods but will, instead, revert to the HTML5 player in circumstances where Flash is not available (e.g. on an iPhone).
In all cases the code generated by this plugin validates to W3C standards. However, it depends on which options you choose at to which DOCTYPE it will validate to.
- IFRAME does not work with XHTML so will ony validate as XHTML transitional (this includes if you use IFRAME as the fallback to EmbedPlus).
- If you include Metadata then you must use the XHTML Strict + RDFa DOCTYPE – in this case it validates.
- If you don’t include Metadata then it will also validate as HTML5 compliant.
The following spreadsheet shows which embed types were tested and to where they validated (or didn’t).
The W3C Markup Validation Service was used to test the above.
YouTube Embed no longer supports the deprecated AS2 YouTube player – this means that some options are no longer available (however, some new ones are). See below for a complete list of the supported parameter for each player type
Artiss YouTube Embed has had around a quarter of a million downloads, with around 40% on the latest release. Every update to the plugin is therefore likely to generate 100k downloads.
The Profile screen is seen by all users wishing to modify their video layout and the demonstration video is critical to checking the results of these changes. If you wish to sponsor this video and make it your video then please contact me for further information.
There is both a standalone video available (this is the main one that you see) and also a playlist.
